Tim Edwards 7276623d3c Corrected the pull-up definition and revised the CSB definition to
match the corrected defintions (namely, pull-up is configuration
0x0801, and pull-down is configuration 0x0c01).

Tim Edwards aba145e0e2 Made modifications in support of changing the hard-coded default
configuration of GPIO 3 (CSB) from a standard input to a weak
pull-up input.

Numerous bug fixes, ending in clean full LVS for both caravel and caravan. (#76)
* (1) Modified the .magicrc file to set a default for PDK if not set in the
environment.  (2) Fixed the user ID programming layout to not leave holes
behind when the script moves the vias around (similar to the handling of
the GPIO defaults block).  (3) Added substrate isolation to gpio_control_block
and fixed the path references to the standard cells.  (4) Fixed the four
missing routes on the Caravan top level.  (5) Reinstated the large rendered
labels for the pads on both caravel and caravan.  (6) Corrected the top
level gate-level netlist for caravan to add the missing pins to the
management core wrapper.  (7) Did the same for the caravan top level RTL.
(8) Created scripts to run full LVS including extracting the management
core wrapper and reading all gate-level verilog submodules.  (9) Moved all
of the LVS scripts to the scripts directory.

* Apply automatic changes to Manifest and README.rst

* Made the changes from pull request #73 as they did not get merged
successfully, and if merged now they will generate conflicts with
this pull request in scripts/set_user_id.py.  So it's easier to
just manually add them to this pull request.

* Apply automatic changes to Manifest and README.rst
